White House Press Secretary Josh Earnest warned Republicans on Wednesday that any threat by Congress of withholding funds would not change President Obama’s decision to issue an executive order to give illegal immigrants amnesty.

In an interview with Breitbart News, Sen. Marco Rubio hinted that if Obama decided to grant executive amnesty to illegal immigrants, perhaps Republicans could block his actions using the budget process. If Democrats in the Senate balked at passing a funding resolution without money to process Obama’s executive amnesty, it could cause a government shutdown.

Reporters asked Earnest if the threat of a government shutdown would change Obama’s decision to offer executive amnesty to as many as five million illegal immigrants.

“No. It won’t, because the president is determined to take the kinds of common sense steps that are required to address the worst problems of our broken immigration system,” Earnest replied.

Earnest said the government shutdown in 2013 over Obamacare was harmful to the economy.
